Sacha Baron Cohen took shameless promotion to a whole other level on the red carpet of the Oscars tonight -- not only did he show up dressed as his character from the upcoming movie "The Dictator" ... but he spilled an urn filled with fake ashes of Kim Jong Il all over Ryan Seacrest ﻿on live television.

Props to Seacrest though ... as he always does, Ryan took the whole thing in stride.
